HARLEY C. ALGER, OF CHICAGO HEIGHTS, ILLINOIS.

SMOKE-RECORDER.

To all whom it may concern:

Be it known that I, HARLEY C. ALGER, a citizen of the United States, and resident of Chicago Heights, in the county of Cook and State of Illinois, have invented new and useful Improvements in Smoke-Recorders, of which the following is a specification.

My invention relates to apparatus of the type described in United States Letters Patent Number 1,093,903 issued to me on April 21, 1914, which may be used for recording or indicating one or more of the constituents of smoke or other gases.

One object of this invention is to produce a smoke recorder which is simple, anotherobject is to produce a device which gives a prompt and accurate record, while another object is to produce a device of this character which is compact in form and eflicient in operation. These objects I accomplish by providing suitable mechanism for forcing a stream of smoke or gas from a nozzle or tube upon a recording member or chart which may be movable, by providing an opening for conducting or carrying away a portion of the smoke supplied to the device, ,thus allowing escape of a portion of the smoke without passing to the recording member and by providing mechanism which causes a series of line records to be made, side by side, which records may be radially located on the recording member or if desired may be spirally located, the former method being shown in the drawings as it is to be preferred in many cases.

Referring to the accompanying drawing, Figure 1 shows a front elevation of are corder embodying, my invention, Fig. 2 1s a sectional view of Fig. 1 on the line XX, while Figs. 3 and 4 show modifications of my invention.

In Fig. 1, my invention is shown mounted within the body 1 of a suitable case, which may have a door 2 with a glass window 3, Fig. 2. The door and glass may be fitted so as to form with the body 1, a substantially air-tight case. A recording member 4, of any preferred type, a recording member of the disk type being shown, rotatably mounted and driven by suitable means, as a clockwork 5,- is positioned within the case.

Smoke may be supplied to the recorder by, a conduit or pipe 6 which may have a separator 7 therein for removing ashes or moisture. A valve 24 may be used to control the passage of smoke; The p1pe 6 may lead or Specification of Letters Patent.

tacle 8 and delivers it to the lower end of the nozzle 9. The nozzle may be mounted on a support 11 extending from the body of the case, the nozzle being pivoted at 12 so that it may oscillate back and forth. A sleeve 14, Fig. 2, having a cam or star wheel 13 and a gear 15 secured thereto is rotatably mounted on a shaft 16 extending from the body of the case. The gear 15 extends inside of the clock work 5 by which it is driven thereby rotating the wheel 13. An arm 17 extends from the nozzle 9 and the end of the arm rests upon the wheel 13, with which it may be held in contact by its weight or a spring 18, in tension, may serve this purpose. The cams of the wheel 13 are of such shape that they give the desired motion to the nozzle 9 and may be of such shape that they lift the end of the arm 17 gradually and then let it fall so that as the wheel revolves, the nozzle 9 may be given a variable oscillating movement, that is, the delivery end of the nozzle, if the motion of the wheel is in a counter clockwise direction, will move at the desired rate or gradually from left to right and then return quickly from right'to left as the arm falls. Smoke issuing from nozzle 9 will make a record showing its relative blackness upon the chart of the recording member and as the recording member revolves and the delivery end of the nozzle oscillates with variable movement as above described, a series of records side by side or substantially radially located upon the chart will be made. The records may be in curved lines due to the oscillation of the nozzle or the speed of the chart in a counter clockwise direction and the dimensions of the other parts may be made such that the records will. be in radial lines. An outlet pipe 19 may serve to conduct from the case any excess smoke as well as the gas left after the constituent of the smoke has been recorded. In order that such an apparatus shall record properly the nozzle Patented Dec. 22, 1914. Application filed April 6, 1914. Serial No. 829,958.

should have-arelatively smallopening for 20 1" g sen ts, more nearly delivering smoke against the chart and if all of the smoke supplied passes through this opening the amount of smoke delivered will be relatively small and considerablev time may elapse after the smoke leaves the vmain flue or st ackithroughwhich smoke'may be passing before this' "smoke will be recorded, especially when the recorder is at some distance from the main flue.

Steam or air admitted art-22 draws smoke throughfthe pipe line 19' may control the operation of ,the ejector.

The opening20' may be provided with a valve'fto control the proportion of smoke allowed to escape as shown at 26, Fig. 3. It should'be noted that the valve 24 of Fig. 1 and thevalve 26 of Fig. 3 are not both needed, as either one may suffice' to control theproportion of smoke delivered through thenozzle or allowed to escape. The opening 20 need not be inside of the case but may take the form shown in Fi g. 4 Where a by pass line 27 leads from the opening or valve 26 to the pipe 19, without passing to the case; I

It will be understood that the proportions of .the device may be so made or various valves may be so adjusted that the record made may be of the correct shades or degrees of blackness-to compare with the Well known Ringlemann standards. Other constructions embodying my invention may be made and I do not confine myself to the exact constructions described.
